Which amplifier should i buy


Hi,
Iv'e already asked , quite similar question , but i would like to clarify my question. So , Iv'e ordered a new speakers, Magico A3 and now i want to buy an amplifier, a tube amplifier. The amount of money that i can allow myself is up to 20,000$. The possibilities that i thought about are : zesto eror 300 / vtl MB -450 series ||| signature / vac phi 170 (two - i mean transform it monobloc) . Those are the options that i thought about till now. Does anyone can recommend which is the best option in this amount of money , it doesn't have to be from the option list that i mentioned.Unfortunately  there are brands that i can not buy in my country (ISR) , for example cat....
Thanks to anyone .

I mean you'd figure anyone with a pair of Magico A3s would engage a preamp by default, right? After all Magico recommends (at minimum) 50 watts / 4 ohms.

I get the tube romance, as every guitar amp I own is all-tune. 

You should test your hearing first... you could save a lot of expensive time and effort.
